Table 2.
Clinical and neonatal outcomes of fresh and vitrified-warmed embryo transfer with SERC(+) and SERC(−) MII oocytes from 252 SERC(+) cycles

SERC smooth endoplasmic reticulum clusters. COC cumulus oocyte complex. MII metaphase second meiosis
NS not significant. ET embryo transfer
P value expressed statistical significance of differences between SERC(+) MII and SERC(−) MII oocytes
aWhen embryos were transfer, we used two embryos that derived from one SERC(+) MII oocyte and one SERC(−) MII oocyte
bThe total is not yet known. In the SERC(−) MII oocytes, each baby resulted from the transfer of a fresh embryo
cNot yet evaluation
